PURPOSE AND USES OF EMBEDDED SYSTEM

PURPOSE AND USES OF EMBEDDED SYSTEM       

    Most of the technology that we use on a daily basis is operated in large part by embedded systems. All of our household appliances, smartphones, uninterruptible heating and security systems, and other electronic devices depend on embedded system technology to function.

WHAT IS EMBEDDED SYSTEM ?8051 MICRO CONTROLLER 

       A sort of computer system known as an embedded system typically integrates into a larger system, gadget, or piece of electronic equipment. They are acomponent of practically every modern piece of technology we use today and consist of a microcontroller that serves a specific purpose within a product.PIC MICRO CONTROLLER
      

     The only way an embedded system can function is if it gets a specific signal in real time. It is a reactive component. It uses sensors and actuators to communicate with the other parts in its environment, and it will only carry out its intended task if it receives the proper response.  AVR ,ARDUINO, ARM

     An embedded system should not be confused with a dedicated system, despite the fact that it frequently dedicates itself to solely carrying out one duty. The name of the system comes from the fact that it is a fixed part of a machine or device that cannot be moved, as opposed to a modular part that may be exchanged for a part with a different function.

       A crucial characteristic of an embedded system is its tiny size, low cost, and low power consumption. Due to the fact that they often only execute one, straightforward job, they are typically simply composed of a power source, communication ports, a CPU, and memory storage, and only minimum software is needed to run and interface with other components.

COMPONENTS OF EMBEDDED SYSTEM :EMBEDDED SYSTEM 

             The bulk of embedded systems have a very straightforward structure made up of just three components.

             The hardware for embedded systems, which is based on microprocessors and microcontrollers, is the first of these. A microcontroller has similar chips, but they are internal to the component rather than being externally linked. A microprocessor is a CPU that uses external chips for memory and peripheral connections.

              Sensors, actuators, and A-D or D-A converters are examples of additional hardware found in embedded systems.

             Along with software and firmware, this hardware enables the embedded system's particular purpose to be controlled. The complexity of this software will depend on the memory and processor speed.

              Real-time operating systems are the last essential element of an embedded system, albeit not all systems have them. Real-time operating systems (RTOS) define and enforce rules about how long particular tasks should take while also carrying out tasks and sending data about them in real-time.

PURPOSE OF EMBEDDED SYSTEM : 

         Embedded systems are used to manage a certain operation inside of a device. Embedded systems are often merely made to carry out this task repeatedly, but more advanced ones can take control of whole operating systems.

         Even while some more sophisticated embedded systems can accomplish a variety of tasks, these are still rather straightforward jobs that don't call for a lot of computing power.

         Embedded systems' inability to be programmed, which makes them reliable once configured to carry out a certain task, means that this is one of their primary distinguishing features. Yet, some devices with embedded systems allow for software upgrades, which allows for the improvement of programmed functions.

         An embedded system is a very dependable electronic component that requires no maintenance and is relatively simple to add to a device because it is created and programmed to serve only one purpose. Although they are a crucial component of a system, they are highly unlikely to malfunction and do not require reprogramming, making them a necessary component of many devices that are needed for a device to simply operate without human interaction, such as home appliances.

TYPES OF EMBEDDED SYSTEM : 

         Even though the majority of these parts have essentially similar designs and functions, there are a number of different types of embedded systems that have unique properties and call for varying degrees of design and installation expertise. You can find embedded systems that fall under more than one of these headings, such as mobile embedded systems with independent functionality.

EMBEDDED SYSTEM IN REAL-TIME :

       Most embedded systems use real-time software, which means they perform the desired output function within a predetermined amount of time. They are most frequently utilised in time-sensitive devices or systems that need a very reliablesystem to make sure that functions are carried out when necessary.

EMBEDDED SYSTEM IN NETWORKING : 

        A network embedded system operates inside a machine or connected device that outputs data to other systems. They are widely used in home security systems where a small device is needed to carry out a straightforward task or react to a particular input before informing a larger, more intricate system that is connected through a network.

EMBEDDED SYSTEM  IN MOBILE APPLICATION :

      Any embedded system employed in portable tiny devices is referred to as a mobile embedded system. They are also present in digital cameras, watches, and music players in addition to smartphones, and are typically relatively basic anddemand little power and memory.

SELF-CONTAINED EMBEDDED SYSTEM : 

      An embedded system that is autonomous or stand-alone operates independently and doesn't need a host system, like a computer, to function. It does not require a connection to any other network or system in order to gather input data, process that data, or carry out the necessary function. Such examples include thermometers or kitchen gadgets like microwaves.
